Abstract

In the case of a semiconductor relay having a control input and an output power switch (1) which can be actuated by means of a control current or a control voltage and opens or closes in accordance with a control signal applied to the relay control input, a first sensor circuit (6), which is integrated with the relay and detects the control current or the control voltage for the output control switch (1), a second sensor circuit (7), which detects the voltage applied to the output control switch (1), and an evaluation circuit, which is connected to the two sensor circuits (6, 7) and optionally delivers an alarm signal, are provided. <IMAGE>
